Hana ʻia ka carbide cemented me ka paʻakikī kiʻekiʻe, refractory metala carbide (e like me WC, TiC, TaC, NbC, a me nā mea ʻē aʻe) me nā mea hoʻopaʻa metala (e like me ka cobalt, nickel, etc.) ma o ka pauka metallurgy kaʻina, ʻo ia ka ikaika kiʻekiʻe loa o ka honua. ʻO ka huila, me ka paʻakikī kiʻekiʻe (89 ~ 93Hm), ka ikaika kiʻekiʻe, ka paʻakikī wela maikaʻi a me nāʻano'ē aʻe.No laila, hoʻohana nui ʻia i ka hana ʻana i nā ʻāpana drill exploration, molds a me nā mea hana.Me ka hoʻomau mau ʻana o ka ʻenehana ʻokiʻoki i ke ala o ka wikiwiki kiʻekiʻe a me ke kiʻekiʻe kiʻekiʻe, ʻo ka ʻoi aku ka kiʻekiʻe a me ka kiʻekiʻe o ka paʻakikī, ke kūpaʻa ʻana, ka pololei o ka wili a me ka ʻoki ʻana i ka maikaʻi o nā mea hana carbide cemented.Ua ulu mālie ka nui o ka carbide cemented mai ka ʻōpala mua a me ka ʻano waena a hiki i ka palaoa maikaʻi, ultra-fine-grained a nanocrystal-grained.
I kēia manawa, hoʻohana nui ʻia ka carbide cemented coarse-grained i nā mea hana geological a me nā mineral, stamping dies, oil drilling, nā hāmare kiʻekiʻe nui no ka hana ʻana i nā daimana synthetic, nā ʻāpana mīkini jet a me nā māla ʻē aʻe;ʻO ka carbide cemented maikaʻi a me ka ultra-fine-grained nā hiʻohiʻona o ka paʻakikī kiʻekiʻe a me ka ikaika kiʻekiʻe, hoʻohana nui ʻia no ka hana ʻana i nā mea hana carbide paʻa, nā mea hoʻokomo indexable a me nā micro drills.
Me ka hoʻomaʻemaʻe ʻana o nā kīʻaha WC i ka carbide cemented, ua hoʻonui ʻia nā waiwai mechanical e like me ka paʻakikī a me ka ikaika, ʻoiai ua emi nā waiwai e like me ka paʻakikī fracture, a ua hoʻololi ʻia ka hana wili e like me ke pale ʻana.
Hoʻohana ʻia ʻekolu mau huila wili daimana nui ʻokoʻa no ka hoʻokō ʻana i nā hoʻāʻo wili ʻana ma lalo o kekahi mau kūlana wili no nā carbide cemented ʻekolu me ka nui o ka palaoa: coarse, fine and ultra-fine.Ma o ke ana o ka mana spindle, ka huila wili a me ka poho o ka mea hana, a me ka mīkini ʻili ʻili o ka ʻili i ka wā o ka wili ʻana, ka hoʻololi ʻana o ka nui o ka palaoa o WC i ka carbide cemented i ka hana wili a me ka hopena e like me ka ikaika wili, ka lākiō wili, a ke kālailai ʻia ka ʻili o ka ʻili.
Ma o ka hoʻāʻo ʻana, hiki ke ʻike ʻia ma lalo o ke kūlana, ʻoi aku ka nui o nā ʻāpana wili o ka ʻili o ka honua, ʻoi aku ka nui o ka ikaika wili a me ka ikaika wili i hoʻopau ʻia e ka wili ʻana i ka carbide cemented coarse-grained ma mua o nā mea o ka fine-grained a me ka ultra-fine. -grained, a piʻi ka ikaika wili o ka ʻili ʻili me ka piʻi ʻana o ka nui o ka palaoa.Hoʻonui ka wili ʻana o ka carbide cemented ultra-fine me ka piʻi ʻana o ka nui o ka palaoa, e hōʻike ana i ka emi ʻana o ke kūpaʻa ʻana o kēia ʻano carbide cemented me ka piʻi ʻana o ka nui o ka palaoa, a me ka roughness ʻili o kēia ʻano carbide cemented ma hope o ka wili maikaʻi ʻana ma lalo. ke emi nei na ano wili like me ka hoonui ana i ka nui o ka palaoa.
ʻO ka hoʻohana ʻana i ka huila wili daimana ke ʻano nui no ka hana ʻana i nā mea hana carbide cemented, he hopena koʻikoʻi ka ʻili ʻana o ka ʻili i ka hana ʻoki a me ke ola lawelawe o nā mea hana carbide cemented, a ʻo nā ʻāpana wili nā kumu nui e pili ana i ka ʻili o ka ʻili. carbide sima
ʻO ka WC-Co cemented carbide specimen i hoʻāʻo ʻia ma ka mīkini wili ʻili, a ʻo ka specimen he carbide cemented ultra-fine-grained sintered e ka ʻenehana HIP.
Ma ka hohonu hoʻokahi, ua hoʻonui ʻia ka ʻala o ka ʻili wili o ka specimen me ka piʻi ʻana o ka nui o ka wili o ka huila wili.Hoʻohālikelike ʻia me ka huila wili 150 #, ʻokoʻa ka ʻili o ka wili o ka laʻana i ka wā e wili ai me kahi huila wili 280 #, ʻoiai e loli hou ka ʻili i ka wā e wili ai me ka huila W20.
